Overthrow The Oppressors

Use this Stratagem before a BLADED COG unit
from your army is selected to fight in the Fight
phase. Until the end of the phase, each time you
roll an unmodified hit roll of 6 for an attack by
a model in that unit, that model can immediately

instead generated on unmodified hit rolls of 5 or 6
when targeting IMPERIUM units, or on
unmodified rolls of 4, 5 or 6 when targeting
